## When to prefer this

Use this endpoint when you need to identify crypto assets losing social attention or mindshare over a 7-day window, particularly for contrarian analysis, risk monitoring, or tracking declining community interest. Prefer this over general news feeds or price-based endpoints when the focus is on social signal decay rather than price action.
